Makeup Air System Installation
Read all instructions before starting installation.
Low voltage wiring should be routed the shortest distance possible to
avoid unnecessary voltage drop.
The current transducer wire shall be a minimum 20 AWG twisted pair.
The current transducer and all control wires shall be kept away from high
voltage wiring to avoid signal interference.
Recommended ambient operating temperature range for the makeup air
system is -20oF (28.8oC) to 140oF (60oC). We recommend that the
installer insulate the entire length of the makeup air system and all duct
work connected to the system to prevent condensation from forming.
The installer is responsible to ensure that air entering gas/oil heat ex-
changers is 55oF (12.8oC) or greater and that air contacting water pipes
or water coils will not cause freezing
The 240V electric heater component (optional) must be installed on a
properly sized, dedicated electrical circuit. The supply fan and FMAC
transformer may be powered via a shared electrical circuit.
Installation Steps:
Each system component must be individually secured to the building
structure.
DO NOT ENERGIZE THE POWER TO ANY SYSTEM COMPONENT UNTIL THE
ENTIRE SYSTEM HAS BEEN INSTALLED AND IS READY FOR SETUP AND
STARTUP.
1. Install intake hood component per its instructions. Take care to locate
the intake appropriately on an exterior wall. Mind the warning and
caution statements in this document.
2. Install the motorized damper component per its instructions, and
connect it to the intake hood with a fast clamp. The damper is
furnished with a 24V AC motor, the damper control method is power
open and spring closed.
3. Install the filter module component per its instructions. Connect the
filter module to the motorized damper with a fast clamp. Make sure
the filter is accessible for cleaning and replacement.
4. Install the supply fan component per its instructions. Connect the
supply fan to the filter module with a fast clamp and a duct transition
(if necessary). The supply fan should be installed and mechanically
supported to reduce the transmission of fan/motor vibration to the
building structure.
5. Install the duct silencer component connecting to the supply fan with a
fast clamp.
6. Install the optional electric heater component (if included) per its
instructions. Instructions which are located in the optional heater box
carton.

8 / 6 kW heater is Stelpro model SDHR8-6K-240VIP-CIR017-OTDD-OEMK-1
10 / 10 kW heater is Stelpro model SDHR10-10K-240VIP-CIR017-OTDD-OEMK-1
12 / 10 kW heater is Stelpro model SDHR12-10K-240VIP-CIR017-OTDD-OEMK
12 / 20 kW heater is Stelpro model SDHR12-20K-240VIP-CIR017-LOTDD-OEMK-1
Default operating mode Setting is W1.
Default temperature setting is 60 oF.
8. Install additional supply ductwork (if necessary). Other suitable supply
duct systems exist. It is recommended that the supply makeup air
not be provided directly to an occupied living space where thermal
discomfort and objectionable noise could result. Be mindful of the
effect that the newly installed quantity of outdoor air will have on the
central HVAC system. Coordinate efforts with the HVAC contractor to
ensure compatibility.
9. Insulate all makeup air system components located where
condensation could form on cold surfaces, including all duct work
connected to the system.
10. Install the FMAC's 24V transformer onto the included 4"x 4"
electrical box. Install the FMAC's controller and transformer w/
4 x 4 box onto the included back plate. Install the back plate into
the included NEMA enclosure. Secure the NEMA enclosure to the
building structure in a convenient, moisture-free, interior location
near the makeup air system.
11. Install the FMAC’s current transducer onto the neutral leg of the
wiring for the compensated exhaust fan (by others). The current
transducer must be installed close to the exhaust fan if not a
dedicated circuit. Install low voltage wire between the current
transducer and the FMAC’s makeup air controller. Reference the
wiring diagram in Figure 5 for wiring termination locations.
Figure 2 . Current Transducer Wiring & Installation
12. Install low voltage wire between the transformer and FMAC’s makeup
air controller. Reference the wiring diagram in Figure 5 for wiring
termination locations. Provide 120/1/60 electrical power to the
transformer.
13. Provide 240/1/60 electrical power to the heater (optional, if included)
on a dedicated circuit. Reference the wiring diagram in Figure 5 for
wiring termination locations. The 10 kW heater uses 41.7 Amps and
the 20 kW heater uses 83.3 Amps.
14. Provide 120/1/60 electrical power to the supply fan. Install wiring
per all applicable codes. Refer to the wiring diagram in Figure 5 for
wiring termination locations.
15. Remove the 3-pronged potentiometer from the wiring terminal block
of the makeup air fan. The 3-pronged potentiometer will not be used
for the makeup air system. Install low voltage wiring between the
FMAC's makeup air controller and the makeup air fan. Refer to the
wiring diagram in Figure 5 for wiring termination locations.
16. Install low voltage wiring between the FMAC's makeup air controller
and the ADC shut-off damper. Refer to the wiring diagram in Figure
5 for wiring termination locations.
